wide ironing table within boiler

How the choice of steam wide ironing table within boilers should distinguish quality? Market top quality steam boilers are very different, so the user selects this product, it needs to identify its quality, then how to distinguish the quality of this product do? First a quality product from the main body of the boiler, it is necessary to identify the quality of the user through the body of the boiler. Body using what kind of material, and what kind of welding process, etc., the details of which are to be noted, that if the boiler has not reached a corresponding requirements in the above welding, when the fire will drain the user . If the material does not meet the corresponding requirements, it is difficult to meet the requirements of thermal insulation.

The installation of a steam wide ironing table within boiler safety valve ensures that when the system pressure exceeds a specified value, the safety valve is opened and a portion of the gas / fluid in the system is discharged into the atmosphere / pipeline so that the system pressure does not exceed the allowable value. This ensures that the system does not cause accidents due to excessive pressure.

Tongchuan City, Shaanxi Province is located in Fenwei plain, it is China's major coal producing area, the unique geographical location determines the Tongchuan coal energy as one of the main economic development. Tongchuan coal to bring rapid economic development, but a large proportion of heavy industry, atmospheric pollution and other issues are very serious. "Winning Blue Sky Battle three-year action plan" published this year, Fenwei plain was a key governance areas. Coal City is not achieved coal, coal is not coal, promote clean heating, Tongchuan City is a serious problem.

Tongchuan party secretary said: "This year Tongchuan 4905 ex situ poverty alleviation relocation of the masses of resettlement housing has been fully completed and turnkey, the actual stay 3763, is a large-scale relocation of mass arrival of new homes in the first year."

After a preliminary investigation, Tongchuan City to improve people's livelihood and environmental protection together, launched a "warm life, warm hearts and minds" of warm winter action. Based on the concept of local conditions, it has been completed in 40 of the city's centralized settlements, reduce operating costs, clear charges. Mastery of natural gas household heating settlements, natural gas boiler wall encouraging people to self-heating; central village of rural resettlement and scattered resettlement households, encourage and guide them to use electric heating and cleaning of heating equipment. All use of clean heating devices are available to the masses 1000 yuan subsidy.

Clean heating, an impact on the masses warm winter, a relationship with Blue Sky Battle Action Plan. It is understood that the city of Tongchuan coal-fired boiler to achieve a global "clear" in 2017. 2018, Tongchuan City by town gas central heating and household heating, rural households in accordance with the appropriate air dispersion of the gas, should the electric power, should be hot is hot, use clean coal coal should guide the masses to reduce the amount of bulk coal use, and the use of clean energy and the masses of poor people winter heating subsidies. Currently Tongchuan City, completed a total clean energy alternative to coal for 27,897, of which 25,196 coal to electricity, coal to gas 2701, the city's clean heating rate of 82%, the basic realization of the coal city does not burn coal, coal is not coal.

According to Eco-Environment Department data show that 11 cities Fenwei plain mean concentration of PM2.5 in October this year to 48 micrograms / cubic meter, down 7.7% year on year. The lowest average concentration of PM2.5 is Tongchuan city, is 38 micrograms / cubic meter.

How steam wide ironing table within boiler operation? Rules applicable to a range of operation of the steam boiler. 2.1 2 content steam boiler process equipment is high-pressure container, the operator must be well-known structures, explanation of the boiler performance and design, operation and obtain operating permits for technical examination in order to operate independently, it must be dressed labor duty products. 2.2 before ignition, each coping member ---- boiler display instrument, an electrical circuit, valves, cocks, pipes, water meter, pump, nozzles and various safety devices according to the procedure to check and confirm that no abnormal situation and leakage It may be started. Closing the hole in advance 2.3 Check the flue, the furnace and no foreign matter before proceeding. 2.4 start, programmed to check that the following do work: water meter; operation of water supply apparatus; low water cutoff operation; action pressure switch; pressure proportional control action; safety valve operation. 2.5 boiler blowdown should be run periodically (once per shift principle), blowdown, or prohibition hand hammer striking thereof with the drain valve opened, flushing water table once per shift. 2.6 boiler operation, the operator leaves his post allowed, when inspection tour should (in general a half-hour inspection, inspection records for one hour). 2.7 inspection tour should wear gloves, can not be touched with bare hands touch the heat conductive member, observe combustion furnace to wear protective glasses. 2.8 alarm has not met Ming, endless self-control or alarm malfunction, the scene was invalid or could not process should be shutdown immediately and report to the leadership process. 2.9 Where any of the following conditions should be treated immediately shutdown a) vapor pressure rises above the pole position, although the strengthening of water supply, steam safety valve has been ruled out, but the pressure continues to rise. b) serious water shortage c) the water level decreases rapidly (although the water supply, but still down) d) water gauge, pressure gauge, safety valves to malfunction. e) the furnace wall is damaged, a large number of smoke f) water supply equipment failure. g) the furnace leaking joints, deformation of the steel sheet, blister or crack is found. h) boiler full of water through drainage is still down. When the rear portion of i) the combustion flue found to have severe, or other polar operator safety risk. j) sudden onset of severe soda steam boiler or furnace Priming severe vibration. 2.10 into the furnace needs repair, you must shutdown before proceeding to cool to room temperature and adequate ventilation, cooling and insulation must take compulsory measures should only be approved by the leadership in case of emergency, and a person responsible for work safety monitoring . 2.11 chain boiler operation, its vapor pressure, air pressure, temperature must not exceed the specified pressure. 2.12 without permission not allowed to remove or destroy any safety valve, safety valve can not be automatically excluded from the operation of steam, shall report to the leadership of the exhaust valve with an artificial lift, and good maintenance. 2.13 When the general lack of water, they should be immediately "called water" tests, such as when the Department of severe water shortages, shutdown should be an immediate ceasefire to stop the water, such as the Department is not serious water shortages, slowly, a small amount of water, but must be strictly monitoring changes in a variety of instruments. 2.14 When shutdown when a cease-fire, before the air pressure drops to zero, the fireman can not leave their posts. 2.15 slag to be cleaned regularly, focused on targeted stacking. 2.16 boiler system must be checked to confirm a variety of instruments, alarms, safety devices intact, correct, sensitive before shift change. 3 Record 3.1 "fireman shift recording."
